IMPROVBD WASHING-Mmmm.

TO ALL WIIOM IT MAY'CONCERN: Be it known that I, JOHN COOPER, of Dublin, in the county ofWayne, and State of Indiana, have invented certain new and useful Improvements in Washing-Machines; andI do hereby declare that the following is a Ifull, clearyand-cxacbdescription thereof, reference being had Yto the accompanying drawings, making part of M this specification, and to the letters of reference marked thereon, like letters lindicating like parts wherever To-enable others skilled n thc art to construct and usemyiinvention, I will proceed to describe it.

My invention relates to washing-machines, and consists of an improvement in the manner of attaching the curved beaters to the central shaft, f or which Letters Patent,'No. 67,725, under date of August 13, 1867, were issued to me for a washing-machine. In thc'drawings- Figure 1 is a view of a side elevation with'one side of the box 4 removed.

Figurel 2 is a view of a vertical Vsection on the line y y of figf `1; and

Figure 3 is a view of a. vertical section on vthe line'g/ y of iig. 1, witlrthe position' of the beaters changed.

-AIn Vthe model accompanying my application for a washing-machine, for which Letters Patent, No. 67,725, were granted me, August 13, 1867, the beaters E were rigidly attached to the shaft I), and it was necessary to givev theshaftD a rocking motion,`s o asnot to carry the articles being washed overwith them.

In constructingmy improved washing-machine, I Vconstruct my box or tub as before, and mount therein the shaft D, Yproviding itwith a bearing` at one end to receive-the pin A upon which it turns,` and at the otherv end .with an'oblong socket, a, as shown in gs. 2 and 3, for receiving the shaft B, by which it is turned, as shownin hg. 1. Before mountingvthc shaft D within the boxC, I make two strips, H, of wood or other suitable material, and attach to their] rigidly a series of bows, E,'shaped as shown iniigs, 2 and 3, and hinge them by hinges F t-o it,ns shownz in Vall'lthefigures. `The shaft maybe turned lby a crank or by gear-wheels, when very rapid motion is desired.

In opeiatingmy4 improved machine 'the'motionof-tlie beaters creates a current on the surfaceof the water which, with the beaters, carries-the upper surface of thecloth'ing across to the otherjside of the'box, and the striking of thc currcntagaiiist the side of the'box creates .a current which descends the side and follows the roundbottom of the berend comes. up on the same vside from which it started. This lowercurrent comingin `contact withthe .lower sur-face 4of theclothing, carries it `to the other sidc. Thisimotion of the current is vconstantly jcarrying' the upper surface in onedirection, while the under surfaceis carried in the opposite direction. The clothing or arfticlesa being washed arc thus kept constantly revolving,'without being carried over by the beaters or rolled into a wad. i

It will readily -beV seen that thc advantages of having-thc beaters thus hinged are that they will 4adjust themselves to thc quantityof clothing in thc box', whether it be lar-ge or small; that they will not c arry the articles being washedlover withthem, and that-'when the shaft'is turned in the opposite direction the hinged `joints will he stiff, and the beaters will haveall the advantages of a rigid attachment.

Having vthus described my invention, .what I claim is The shaft I), having-the 'beaters hinged tor it as described, whenr'constructcd and arranged to operate substantially vas set forth. i 'i t u i r JOHN COOPER. y Witnesses: l
